L2TP over IPsec wont connect

Hello,

 

We are using Sophos UTM 9. We have PPTP VPN Setup which works fine however we would like to use L2TP over IPsec also.

 

I have set this up and trying to connect via Windows 10 built in VPN app but when connecting I am getting the below errors. We are using a Draytek 2862 if that helps. if anyone could advise what we need to do to fix this it would be very helpful

  • Hi Phil and welcome to the UTM Community!

    L2TP/IPsec can't connect if the UTM is behind a NAT.  Can you put the Draytek into bridge mode so that you get a public IP on the UTM?

    Cheers - Bob
